Figure: paronychia  (http://en.wikipedia.org/wiki/Paronychia#mediaviewer/File:Paronychia.jpg) Typical chronic paronychia. Caitlin McAuliffe There are a couple of ways to do this. The simplest, least invasive way (and the one I teach my patients!) is to soak the affected digit in warm water and then, once the skin has softened, to gently separate the skin of the lateral nail fold from the nail itself using a sterile flat, blunt-edged instrument. This technique is pretty old; in fact, while looking for images to use in this post I came across this picture from “The Practice of Surgery (1910)” Chronic paronychia tends to be more difficult to diagnose. A potassium hydroxide (KOH) test, in which a smear is extracted from the nail fold, can sometimes confirm a fungal infection. If pus is involved, a culture is usually the best way to confirm the presence of fungus or other, less common infective agents.

Your Health Resources Management of acute paronychia is a surprisingly evidence-light area. Firstly, for a simple acute paronychia, there is no evidence that antibiotic treatment is better than incision and drainage. If there is associated cellulitis of the affected digit (or, Heaven forbid, systemic infection) or underlying immunosuppression, then antibiotic therapy should be considered, but your first priority ought to be to get the pus out.

Dermatology Advisor LinkedIn Pregnancy and Childbirth Chronic paronychia usually causes swollen, red, tender and boggy nail folds (Figure 4). Symptoms are classically present for six weeks or longer.11 Fluctuance is rare, and there is less erythema than is present in acute paronychia. Inflammation, pain and swelling may occur episodically, often after exposure to water or a moist environment. Eventually, the nail plates become thickened and discolored, with pronounced transverse ridges.6,8 The cuticles and nail folds may separate from the nail plate, forming a space for various microbes, especially Candida albicans, to invade.8 A wet mount with potassium hydroxide from a scraping may show hyphae, or a culture of the purulent discharge may show hyphae for bacteria and fungal elements. C. albicans may be cultured from 95 percent of cases of chronic paronychia.6 Other pathogens, including atypical mycobacteria, gram-negative rods and gram-negative cocci, have also been implicated in chronic paronychia (Table 1).6 21 This information is provided by the Cleveland Clinic and is not intended to replace the medical advice of your doctor or healthcare provider.

This can lead to the swelling and gradual deterioration of the epidermal layer. Unlike acute paronychia, most chronic infections are caused by the fungus Candida albicans and other fungal agents.

About us Chronic paronychia responds slowly to treatment. Resolution usually takes several weeks or months, but the slow improvement rate should not discourage physicians and patients. In mild to moderate cases, nine weeks of drug treatment usually is effective. In recalcitrant cases, en bloc excision of the proximal nail fold with nail avulsion may result in significant cure rates. Successful treatment outcomes also depend on preventive measures taken by the patient (e.g., having a water barrier in the nail fold). If the patient is not treated, sporadic, self-limiting, painful episodes of acute inflammation should be expected as the result of continuous penetration of various pathogens.
